Q1. What roles can the HFE82V-60 play in an EV?
A: Per the HFE82V application matrix, it serves as main relay, precharge relay, fast-charge relay, normal-change relay or auxiliary relay in passenger EV/PHEV, HEV, bus, low-speed EV and logistics vehicle high-voltage systems.
Q2. What is the voltage rating - 450V, 750V or 1000V?
A: The standard variant is rated 450VDC load voltage; a 750VDC high-voltage variant is available. Max. switching voltage is 1000VDC, giving ample margin above both. Contact us to match the variant to your battery pack voltage.
Q3. How much fault current can it break?
A: Max. breaking current is 600A at 450VDC (1 operation) - well above the 60A continuous rating and the 360A/2s overload point, protecting the pack in fault scenarios.
Q4. What coil options are available?
A: 12VDC or 24VDC, both 4.5W. Pick-up voltage is ≤9V (12V coil) or ≤18V (24V coil); operate time ≤30ms and release time ≤15ms at rated voltage.
Q5. How long does it last?
A: Electrical endurance is 800 operations at 450VDC/60A (or 7.5×104 operations at 20VDC/60A), with mechanical endurance of 2.5×105 operations. Endurance curves are available on request.
Q6. Is it certified and vehicle-grade?
A: Yes - UL, CUL, VDE, TÜV and CQC certified. It operates from -40°C to +85°C, withstands 10~500Hz / 49m/s2 vibration and 196m/s2 functional shock, meeting passenger vehicle environment requirements.
